Which term refers to a network that provides secure access to the corporate
office by suppliers, customers, and collaborators? - -Extranet
-A small business user is looking for an ISP connection that provides high
speed digital transmission over regular phone lines. What ISP connection
type should be used? - -DSL
-An administrator is trying to configure the switch but receives the error
message that is displayed in the exhibit. What is the problem?
Switch> config t
Error - -The administrator must first enter the privileged EXEC mode before
issuing the command.
-Which keys act as a hot key combination that is used to interrupt IOS
process? - -Ctrl-Shift-6
-A network administrator is configuring access control to switch SW1. If the
administrator uses Telnet to connect to the switch, which password is
needed to access user EXEC mode?
SW1(config)# enable password letmein
SW1(config)# enable secret secretin
SW1(config)# line con 0
SW1(config-line)# password lineconin
SW1(config-line)# login
SW1(config-line)# exit
SW1(config)# line vty 0 15
SW1(config-line)# password linevtyin
SW1(config-line)# login
SW1(config-line)# end
SW1# - -linevtyin
-A network administrator enters the service password-encryption command
into the configuration mode of a router. What does that command
accomplish? - -This command prevents someone from viewing the running
configuration passwords.
-What is the purpose of the SVI on a Cisco switch? - -The SVI provides a
virtual interface for remote access to the switch.
, -Which message delivery option is used when all devices need to receive the
same message simultaneously? - -Broadcast

and IP

medium? - -It is encapsulated in a Layer 2 frame.
-What type of communication medium is used with a wireless LAN
connection? - -Radio Waves
-In addition to the cable length, what two factors could interfere with the
communication carried over UTP cables? (Choose Two) - -Crosstalk and
Electromagnetic Interference
-What are the two sublayers of the OSI model data link layer? (Choose Two)
- -LLC and MAC
-A technician has been asked to develop a physical topology for a network
provides a high level of redundancy. Which physical topology requires that
every node is attached to every other node on the network? - -Mesh
-What type of communication rule would best describe CSMA/CD? - -Access
Method
-If data is being sent over a wireless network, then connects to an Ethernet
network, and eventually connects to a DSL connection, which header will be
replaced each time the data travels through a network infrastructure device?
- -Data Link
-What best described the destination IPv4 address that is used by
multicasting? - -A single IP multicast address that is used by all destinations
in a group.
-In an Ethernet network, when a device receives a frame of 1200 bytes,
what will it do? - -Process the frame as it is.
-What will a Layer 2 switch do when the destination MAC address of a
received frame is not in the MAC table? - -It forwards the frame out of all
ports except for the port at which the frame was received.
